FIELD: agriculture.

SUBSTANCE: in the drain well 1 a chamber 11 is located, communicated with the outlet orifices 12 and 25, and a container 13. In the chamber 11 a float articulation linkage is placed, the rod 18 of which is passed through the orifice 12 into the container 13, in which the cone valve 14 with the load 15 is placed. The container 13 through the pipeline 16 is connected to the outlet drain 4. The bottom of the chamber 11 is communicated with the drain well 1 by the inlet opening 17 and is made in the form of a valve 23 and a float sensor 22 interconnected with the rod with the ability of axial displacement. The inlet opening 17 of the float sensor 22 is formed with projections-limiters 24 with windows. The housing 10 of the shut-off device has a recess in which a pipe 26 with a spring 27 with a screw 28 is placed. The spring 27 is placed in the cavity of the flexible sleeve 29, which serves as protection from clogging with debris and deposits. The sensing element in the form of a spring 27 supports the valve 3 in opening and closing the opening 9 in the seat of the housing 10, which eliminates the shock loading of the valve on the seat in the housing 10.

The invention relates to agriculture, in particular to the reclamation and can be used for automatic regulation of the level of groundwater in closed drainage-humidification systems, as well as when adjusting the level of water in the upper dam tailrace structures on irrigation and drainage-channels humidifier.

A well-known regulator of the groundwater level, installed in the observation well and containing a Poppet valve with a float actuator, the housing of which is mounted on the cap drains, the camera installed in her float and level sensor ground water in the form of tubular filter (USSR Author's certificate No. 763519, CL E02B 11/00, 1980).

The known device is difficult to manufacture, in the process of operation due to sedimentation and sogrevaniya gauge tubular filter is not provided with sufficient accuracy maintaining predetermined pressures, wherein the tubular filter is located at 3-5 m above the well in the characteristic point depression curve, ie may not work in all range of regulation of drainage water depending on fluctuations in water level in the drainage system.

Furthermore, the design of the movable cylinder Poppet valve interconnected to move relative to each other in welded housing complex in operation and the drive�t to significant efforts to overcome the hydrostatic pressure in welded casing, acting on the entire area on the Poppet shutter when it is opened. These efforts reduce the reliability of operation of the device, and hence the reliability of its operation. It is also unreliable due to friction of the rack on a vertical rod, debris and the lack of a control system for a full trim lever of the device in two opposite directions, causing the randomness of the selection of its provisions.

The closest of the analogues adopted for the prototype, is a device for controlling the level of groundwater containing a well with in it the cap drains are fitted with a valve body, the float actuator mounted in the chamber, which communicates with the well and the pipeline connected with the drain (USSR Author's certificate No. 1013560, CL E02B 11/00, 1983).

The disadvantage of this device is that it cannot control the downstream and, therefore, cannot be used in a cascade of such structures along the length of the manifold, while in the process of operation does not seem accurate and flexible regulation of the groundwater level due to constant manual opening or closing of the valve in the side wall of the chamber, which adversely affects the yield of crops. In addition, the lever arm � throttle directly in the pit complicates the design and increases the error in the stabilization of a set of consumption and the need for customization of the float with the work of spillway gate in each specific when applied in real conditions. It is also unreliable due to friction of the piston in the slide when hit by debris and sediment and the lack of a control system for complete equilibration of the float actuator when the shutter closes, and unreliable due to friction of the piston in the slide when hit by debris and sediment, it is difficult to operate.

The proposed device aims to eliminate these drawbacks by design, which allows to reduce the amount of hydrostatic pressure during opening and closing of the closure member in a valve at the expense of the overall design and balance system float part, in particular, for quick closing shut-off valve outlet drains at the time of draining of water from the float chamber; to exclude the ingress of debris and sediment on the driving elements of the device, which increases the operational reliability, the quality and accuracy of regulating water in drainage system.

The proposed device is simple, modern and progressive in the constructive elements and materials (valve, elastic sleeve, the spring, the level sensor). The spring Adjuster is to control the pressure on the float actuator, it not only reduces hydraulic shock, but performs the role of supporting (holding) the constructive element. The force of the spring lowers �poplavkovyi drive, and the valve securely closes the discharge hole drains, i.e. it compensates for the torque of the load on the float actuator via a lever system, and high reliability operations. In addition, over cap closure member is a bellows, which prevents leakage of water from the well in the drains.

The purpose of the invention - increase reliability by reducing the stress on the float actuator.

This object is achieved in that the device for controlling water level in a closed drainage system, including drainage well with in it the cap drains are fitted with a valve body, the float actuator mounted in the chamber, which is connected to the well and the pipeline is connected with the drain, the locking body contains in the bottom of the sump to the nozzle, the cylindrical shape from the outside of the body in which the sensing element in the form of a spring attached at one end to the valve, and the other is connected to the position mechanism of the spring, secured in the bottom of the pipe with the possibility of its vertical movement by changing the position of the valve on the outlet of the housing, wherein the valve is installed between the input and output channels of the housing, and the output channel is connected to the output drains.

In addition, the mechanism of the position of the spring in the form of an adjusting screw rigidly secured to the bottom of patrol�from the bottom of the well.

In this case the inlet opening of the chamber has projections, limiters, periodically interacting with float sensor associated with the valve.

The drawing shows a device for controlling water level in a closed drainage network, General view, in the filling mode.

The device includes a drainage well 1 connected to input 2 drains and shut-off valve 3, which regulates the flow of water through the exit drains 4. Shutoff valve 3 with the rod 5 is passed through the guides 6 in the cap 8 provided with a bellows 7 of elastic material. The valve 3 closes the outlet opening 9 in the housing 10, informing drains with 4 well 1. The well 1 is provided with a flow chamber 11, a connecting exhaust orifice 12 with an additional capacity of 13. Outlet calibrated orifice 11 is blocked by the valve 14, provided with a load 15, to increase its mass. The receptacle 13 by a conduit 16 is connected to the output of the drain 4 and the inlet opening 17 - drainage well 1. The valve 14 is made in the form of a cone, the vertex of which is attached a rod 18 on which is fixed the float 19 by means of a latch 20, and the float 19 is placed in the chamber 11, which, in turn, the rod 18 is connected to the lever body 21 with the rod 5 of the stop valve 3. Stock 5 shut-off valve 3 may be of the screw, allowing the possibility of setting�s valve 3 upward or downward displacement of the float 19 in the chamber 11 with the rod 18, moreover, the lower end it is connected with the valve cone 14 with the load 15, the latter is placed below the bottom of the chamber 11 in the container 13.

Float sensor level 22 with a valve 23 disposed in the inlet hole 17 made in the chamber 11 is communicated with the drain well 1, the inlet opening has projections 24 with Windows and periodically interacts with float sensor, level 22, in the highest position associated with the valve 23. The choice of float sensor 22 levels allows you to push the sensor 22 to the lugs of the limiters 24, through the holes where the water enters the chamber 11. The kinematic connection between the float 19 and the shut-off valve 3 is in the form of a lever 21 pivotally connected with the drain well 1. The combination of the float 19 on the rod 18, passed through a calibrated orifice 12 and a valve 14 with a cargo of 15 variable mass, allows to avoid bias in the vertical displacement. On the side wall of the chamber 11 is calibrated orifice 25 which communicates with the well 1.

At the base of the housing 10 of the locking body recess in which is fixed a nozzle 26 of a cylindrical shape, which is placed inside the sensing element in the form of a spring 27 with the locking screw 28, which is fastened to the bottom of the pipe 26. The valve closure element 3 and the pipe 26 are connected by a flexible hose 29, which covers progi�27 with the possibility of free movement of the rod 5 of the valve 3, the spring 27 one end rigidly attached to the valve 3. A spring 27 is mounted coaxially to the rod 5 of the valve 3 at a predetermined distance, to overcome the hydrostatic pressure of the water on the float 19, with the gradual drawdown of the camera 11, i.e., the valve 3 occupies a position in which the discharge of water through the hole 12 from the chamber 11 against the force of the hydrostatic resistance of the float 19 with the load 15. The spring 27 not only performs the role of supporting structural element, but also reduces water hammer when closing the valve 3. This force is balanced by a spring in a closed cavity flexible hose 29 with the mechanism of changes in the form of an adjusting screw 28 are rigidly secured to the bottom of the pipe 26.

A device for controlling water in a closed drainage system operates as follows.

As the water enters the well 1 the device is in position when the seat closure member biased by a spring 27, the valve 3, the float 19 with the load 15 is in its lower position. In the installed position record the length of the stem 5 of the valve 3. Under the action of an adjusting screw 28, is fixed to the vertical pipe 26, fix the adjusted force of the spring 27. Flexible hose 29, which covers the spring 26, is used to protect her from falling debris and sediment in the work of Dr.�steering device. Incoming water fills the pit 1, level increases, and a rise in the water level in the well 1. Owing to the location of the float sensor 22 is below the bottom of the chamber 11 at a certain height, by ascent of the float sensor 22, the valve 23 thereby opens the inlet opening 17, increasing the flow of water into the chamber 11. By increasing the difference of level in the chamber 11 of the hydrostatic pressure of water increases, the float 19, following the water level in the chamber rises and simultaneously raises the valve 14 and the load 15 in additional capacity 13. Reaching the stop in the bottom of the chamber 11, the valve 14 closes the outlet opening 12, filling the chamber 11 is completed. The balance lever mechanism is broken and the rod 5 presses on the valve 3 and the opening 9 of the housing 10 is opened. The bellows 7 is hermetically isolates the cavity of the cover 8 from the water in the well 1, and prevents the deposition of suspended particles in the guideway 6. The locking body (body) 10 is also not zamulyuyetsya sediments. Maintaining a predetermined opening 9 holes causes an increase in the flow area at the seat of the valve housing 10. Thus, when the pressure in the well 1, it is obvious from the schematic diagrams of the regulator 3, the sensor element is provided in the form of a spring 27 placed in the recess of the socket 26 with the reg�Liovochkin screw 28. Consequently, the discharge increases in groundwater drains 4.

By lowering the groundwater level below a given well 1 is emptied, the float sensor 22 is lowered, the valve 23 closes the outlet opening 17. Consequently, the chamber 11 remains for some time filled with water - with a delay, then a decrease through a calibrated hole 25 located in the wall of the chamber 11, and the water gradually flows into the well 1, which opens the outlet opening 12 of the valve 14. Water from the tank 13 through the pipe 16 enters the outlet drains 4. Moreover, the hydraulic regime in the chamber 11 is characterized by a smooth gradually fading change of the expenditure, up to the complete emptying it, which contributes to the presence of the uncompressed spring 27 in the cavity of the nozzle 26 in the direction of compensation of the moment of movement on the float 19 with valve 14 and the load 15 through the lever-hinge mechanism. Moreover, the necessary time delay emptying water from the chamber 10 allows complete discharge of water from well 1 in waste drains 4. If the water in the well 1 flows into the outlet drains 4 by volume exceeding the volume of water in the chamber 11, the delay time is adjustable as long as the flow decreases in the well 1 due to the presence of sensitive elements of the device. The equilibrium of the system is broken again. The result comes in the d�iunie stock 5, and valve 3 closes the outlet opening 9. Maintaining valve 3 bogatoi spring 27 in the pipe 26 reduces hydraulic shock valve associated lever mechanism with float actuator consisting of the elements 19, 14, 15, and maintains the pressure of the float in the chamber is more efficient due to the presence of the control sensing element 27 placed in the pipe 26. The spring 27 will not affect sediment deposition in the presence of a flexible hose 29, covering it in the pipe 28, and the end of the spring connecting the valve 3 with the end face of the latter.

Due to the connection of the valve 3 with the spring 27 in the pipe 26 is provided with a damping effect on the float actuator and buoyancy of water on the float 19 is equal to the volume of the immersed part, prevents abrupt closure (retention) valve 3 holes 9 in the saddle, which also improves the accuracy of regulation. After emptying of the chamber 11 and the tank 13, the device is ready for a new cycle of operation.

Thus, the constancy of runoff in the drains 4 when the pressure change in the well 1, it is obvious from the schematic diagrams of the regulatory body 3 associated with the sensitive element (spring) 27 and a flexible sleeve 29.

The advantage in comparison with the prototype is to increase the control accuracy, robustness and increasing the operational reliability�and due to the lack of friction in the movements of the rod and the closure member relative to each other, on that can influence sediment and debris, and improves the reliability and progressiveness of structural elements. The opening of the closure member occurs only after emptying the float chamber. Changing the sensing element is performed by changing the compression of the spring by screwing the screw. This allows to regulate automatically, with a simple system of nodes and washing takes place under the pressure of the water.

SUBSTANCE: invention relates to mining industry, and namely to development of flooded mineral deposits, as well as it can be used at unwatering of foundations and in hydraulic engineering. In order to protect an open pit against underground water influx, the main horizontal drain wells 4 are constructed normally to open pit 2 side 1. At least two opposite lying additional side horizontal drain wells are constructed out of each main horizontal drain well 4. Out of points 5, 6, 7 on the main horizontal drain wells 4 there constructed to one side in the direction of adjacent wells 4 to the right are additional side horizontal drain wells 8, 9, 10. Out of the same points 5, 6, 7 on adjacent wells 4 there constructed to the left are additional side horizontal drain wells 11, 12, 13. All the additional side horizontal drain wells are constructed till their mutual intersection and formation of a closed drain circuit. All wells are constructed at the bottom of the drained water-bearing horizon.

EFFECT: providing increase of entrapment degree of breakthrough of underground water to open pit sides and reducing drilling volumes of the main horizontal drain wells owing to enlarging distance between them.
